Engineering Construction Pipeline Connection Solutions

Engineering Construction Pipeline Connection Solutions from One Manufacturing Source

Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd builds the equipment that carries a pipe from raw stock to a tested, sealed joint. Our Pipe Fabrication & Installation Equipment manufacturer range covers cutting, threading, joint tightening, hole drilling, hydrostatic testing and the compressed-air supply that drives the tools on site. Established in 2010, we operate a 10,000 m² facility in Hangzhou with more than 100 employees, and we have released nine generations of intelligent threading machines supported by more than 30 patents and the National High-tech Enterprise title.

Our Engineering Construction Pipeline Connection Solutions serve fire protection engineering, building services, municipal work, petrochemical piping and industrial plant installation. The range follows the order of work on a contract: cut the pipe square, produce the thread, tighten the joint, drill the branch outlet, pressure-test the line, and keep clean compressed air available for the pneumatic tools that support the crew.

Our Pipe Fabrication and Installation Equipment Range

Where Each Machine Fits in the Pipeline Workflow

A piping contract moves through predictable stages, and each stage places different demands on the tooling. We build the range so that a contractor can equip a full workflow from one source, with matching thread forms, die sets and consumables across the machines.

• Pipe cutting. The Variable Frequency Cold Saw uses a permanent-magnet variable-frequency motor and a 14" carbide-tipped blade to deliver spark-free, burr-free cuts with a smooth edge that needs no secondary finishing. Cutting speed is adjustable to the material, and the 0–45° angle setting handles mitred work.
• Thread production. The Intelligent Threading Machine identifies pipe diameter automatically and sets the tool without manual adjustment, covering DN15–DN100. Threading time is as fast as 4 seconds on 15–25 mm pipe, and one machine can process 1,500–2,000 threads in an eight-hour shift.
• Joint assembly. The Intelligent Pipe Tightening Machine applies electric screwing with adjustable torque and automatic return, which keeps joint make-up consistent where manual wrenching is slow and uneven.
• Branch outlets. The Fire Pipe Drilling Machine produces φ16–φ114 mm holes on DN15–DN200 pipe, with a clamping fixture holding hole position and overload protection stopping the tool when it meets a hard pipe wall.
• Line testing. The Electric Pressure Test Pump delivers adjustable 0–6 MPa hydrostatic pressure, stops and holds automatically at the set value, and relieves pressure to protect the equipment under test.
• Air supply. Oil-Free Piston Air Compressors feed pneumatic tools and installation work with air that carries no oil residue, removing the need for regular oil maintenance.

Pipe Materials and Thread Forms

Our threading equipment is set up for carbon steel, galvanized, stainless steel, aluminum and copper pipe. Thread coverage includes British standard pipe thread, American standard pipe thread, metric thread and non-standard profiles produced to a customer drawing. Because the die sets are matched to the machine working range, the same machine can move between material types and thread standards without a change of platform.

Capacity, Accuracy and Repeatability

Capacity is quoted at the working point, not as a peak figure. The dual-speed electric pipe threaders give operators a low-speed setting for larger diameters and harder material and a higher setting for smaller, softer pipe, which protects thread quality while keeping cycle time down.

• SQ65 dual-speed electric pipe threading machine: 15–65 mm (1/2"–2.5"), 25/40 RPM, 1300 W rated input, 220 V, 50/60 Hz, 75 kg net weight.
• SQ100 dual-speed electric pipe threading machine: 15–100 mm (1/2"–4"), 15/33 RPM, 1100 W rated input, 220/380 V, 50/60 Hz, 145 kg net weight.
• Cold saw blade life: over 3,500 precise cuts per blade under normal production conditions.
• Pressure test pump: 0–6 MPa adjustable output with automatic pressure-hold at the set value.
• Fire pipe drilling: φ16–φ114 mm hole range across DN15–DN200 pipe diameters.

Configuration Options and Control Integration

We configure each machine around the working point of the project rather than a single catalogue number. Automatic diameter recognition and automatic tool setting on the intelligent threading machine remove the manual adjustment step that slows a crew and introduces variation between operators. On the tightening machine, torque is adjustable and the head returns automatically once the joint is made up.

Drive and control choices follow the site supply and the material mix: 220 V single-phase or 220/380 V three-phase input, 50/60 Hz, dual-speed or variable-frequency speed control, and overload protection that reduces speed or stops the tool when cutting resistance rises. The F1200 air compressor adds intelligent auto start-stop, shutting down at the preset pressure ceiling and restarting when pressure falls, which avoids idle running and reduces wear.

Installation, Utilities and Operator Safety

• Power supply matched to site availability: 220 V single-phase for the SQ65 threader, cold saw, drilling machine and test pump variants; 220/380 V for the SQ100 threader and the 380 V three-phase pressure test pump.
• Mobile bases and wheeled frames on the pressure test pump and heavier machines allow movement between floors and work fronts without a lifting plan.
• Pipe clamping fixtures on the drilling machine and quick clamping devices on the cold saw hold the workpiece during the cut or hole, which supports both accuracy and operator safety.
• Safety guard on the cold saw, overload protection on the saw and drilling machine, and automatic pressure relief on the test pump limit exposure during normal operation.
• Oil-free compressor output keeps the air line free of oil carry-over, which matters where pneumatic tools work on pipe surfaces that will later be painted, lined or tested.

Quality Control, Acceptance and Compliance

Our equipment is issued with an Attestation of Conformity covering the Machinery Directive and the Electromagnetic Compatibility Directive. The patent portfolio behind the range covers pipe fitting connection equipment, steel pipe clamps for thread processing equipment, threading cutterheads, pipe twisting machines and portable electric clamps, and the company holds the National High-tech Enterprise title.

Acceptance is agreed against measurable outputs rather than a general statement of quality: thread form and gauge fit, cut face finish, hole diameter and position, and pressure-hold stability at the set test value. Where a project requires a specific thread standard or a non-standard profile, the die set and the acceptance gauge are confirmed together before the machine is released.

Information We Use to Configure Your Solution

A configuration that fits the first time depends on a short set of project inputs. We use the following to select the machine family, the working range and the tooling package.

• Pipe schedule: outside diameter and wall thickness range, plus the largest and smallest joint on the contract.
• Material: carbon steel, galvanized, stainless steel, aluminum, copper or PVC, including any mixed-material scope.
• Thread standard: BSPT, NPT, metric or a non-standard profile, with the gauge or fitting that will be used for acceptance.
• Production target: joints or threads per shift, and whether the machine works in a workshop or moves between site positions.
• Site utilities: available voltage, phase and frequency, and whether compressed air is already installed.
• Test requirements: hydrostatic test pressure, hold duration and the equipment under test for pressure test pump selection.
• Tooling and consumables: die sets, carbide blades, drilling bits and spare parts to be included in the delivery scope.

Maintenance, Spare Parts and Documentation

Serviceability is designed into the range. Die sets, carbide-tipped blades, drilling bits and the portable electric clamps used on threading machines are supplied as separate items, so a worn consumable does not take a machine out of service. Oil-free compressor design removes the oil change routine entirely and reduces the maintenance schedule to filter and pressure-system checks.

We provide training for buyer partners and their operators, covering machine setup, thread and cut quality checks, and routine maintenance. Documentation and delivery scope are confirmed with the order, including the machine configuration, tooling package and the spare parts list that supports the first operating period.

Frequently Asked Questions

What pipe diameters and thread forms can Xinabo threading equipment handle?

The intelligent threading machine covers DN15–DN100. The SQ65 dual-speed electric threader works from 15–65 mm and the SQ100 from 15–100 mm. Thread forms include British standard pipe thread, American standard pipe thread, metric thread and custom non-standard profiles produced to drawing.

Can one machine produce both BSPT and NPT threads?

Yes. The SQ65 and SQ100 machines support both BSPT and NPT, and each is supplied with three die sets that cover the full working range — 1/2"–3/4", 1"–2" and 2.5" on the SQ65, and 1/2"–3/4", 1"–2" and 2.5"–4" on the SQ100.

How do you match a cold saw or drilling machine to a fire protection project?

We match on the cut list and the branch schedule. The cold saw is selected for the pipe and profile sizes to be cut and the mitre angles required, while the fire pipe drilling machine is specified by hole diameter and pipe range — φ16–φ114 mm holes on DN15–DN200 pipe, with a clamping fixture sized to the pipe diameters on site.

What pressure range does the electric pressure test pump cover?

The 380 V three-phase electric hydrostatic pressure test pump delivers 0–6 MPa adjustable output. It stops and holds automatically when the set value is reached and includes automatic pressure relief protection to prevent over-pressure damage to the equipment under test.

Do you supply die sets, blades and spare parts separately?

We do. Threading dies, carbide-tipped cold saw blades, drilling bits and the portable electric clamps used on our threading machines are available as separate supply items, so consumables can be stocked against the project schedule.

What information do you need to prepare a configuration and quotation?

Send the pipe diameter and wall thickness range, material, thread standard and acceptance gauge, production target per shift, site voltage and frequency, hydrostatic test pressure and hold duration, and the tooling or spare parts you want included. With those inputs we confirm the machine family, working range, tooling package and delivery scope.
